The phrase "layers of powder" is correct and usable in written English.
It can be used to describe a substance that is composed of multiple thin layers of powdered material, often in contexts like cooking, cosmetics, or geology.
Example: "The artist applied layers of powder to create a textured effect on the canvas."
Alternatives: "strata of powder" or "coats of powder."
This is usually done using lasers or electron beams, but another technique involves using a polymer to adhere layers of powder together.
Selective laser melting (SLM) is a Rapid Manufacturing technique in which parts of complex shape are produced by selectively melting layers of powder.
During fabrication, a printer head is used to print a liquid on to thin layers of powder following the object's profile as generated by the system computer.
Selective laser melting (SLM) is an additive manufacturing technique in which functional, complex parts can be created directly by selectively melting layers of powder.
Selective laser melting (SLM) is an additive manufacturing process in which functional, complex parts are produced by selectively melting consecutive layers of powder with a laser beam.
The company claims it can do this 20 times faster than is possible by using a laser to melt successive layers of powder spread onto a flat bed in the process called laser sintering, which is now the most common way metal items are 3D-printed.Once the newly built structure has cooled, it can be machined.
They build up layer upon layer of a plastic, ceramic or metal, either by squirting the material out of a nozzle in a controlled way or by melting successive layers of powders using a laser.
Catalysts are commonly deposited on an internal reflection elements (IRE) as layers of powders or as films (e.g. metal film), and they are exposed to the liquid phase reactants.
A laser positioned above the plate melts one layer of powder to the layer below.
Each layer of powder is as thin as a human hair.
One layer of powder, about 20 to 50 microns thick, gets spread across a plate.
